An Empirical Comparison between Objective and Subjective Measures of the Product Innovation Domain of Corporate Entrepreneurship
开发了公司创业中产品创新领域的客观测量（基于档案数据）和主观测量（基于问卷），发现两者均可靠且无显著差异，对学术研究和管理实践有参考价值。
Developing both subjective and objective measures of the concept of corporate entrepreneurship would be of interest to the field of entrepreneurship. This study (1) develops an objective measure of one domain of corporate entrepreneurship, product innovation, using archival data, and (2) uses a self-report questionnaire as a subjective measure for the same domain. Both the subjective and objective measures were statistically reliable and no significant differences between the two measures were found. Implications for both academic researchers and practicing managers are noted.
